NAME

Bencher::Scenario::LogGer::Overhead - Measure startup overhead of various codes

VERSION

This document describes version 0.012 of Bencher::Scenario::LogGer::Overhead (from Perl distribution Bencher-Scenarios-LogGer), released on 2017-08-04.

SYNOPSIS

To run benchmark with default option:

% bencher -m LogGer::Overhead

For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.

DESCRIPTION

Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
